I care for a 3 yr old girl who cries every day. EVERY DAY. Without fail. She comes on alternating weeks due to her parent's separation agreement, but has been coming for 2 years. Before the parents separated, she came 2 days every week. She arrives in the morning happy and plays well for most of the day but guaranteed that at some point she will stop what she is doing and cry...and cry and cry.... She says she misses her dad, or her mom, or another dck that isn't there, but most of the time, it's for her dad- very much Daddy's little girl. And the crying will go one for some time despite me talking to her, holding, hugging her, redirecting. I have explained to her (everyday) that her daddy is working and will come get her when work is done. i tell her what will happen thruout the day so she understands at what point her dad comes to get her.

What do you think it is? What else can i do?
